Hi Jonathan,
It seems that database tables are not getting updated despite of running report /RPM/FICO_INT_PLANNING.
Can you please check and confirm this whether table RPM_FIDATA is getting updated.
If not, I would suggest to run report RPM_FI002 before running /RPM/FICO_INT_PLANNING.
Let us know if this works.
Best Regards,
Aditya
